Tan GH, Chong CL

Environ Monit Assess, 1993 Feb;24(3):267-77.

The Klang River Basin is located in the most densely populated region in Malaysia, with its heavy concentration of industries and population. A systematic study of the pollution to this river system caused by phenolic compounds have been carried out under this project. Analyses of water samples from the Klang River by high performance liquid chromatography (HPLC) with an ultraviolet (UV) detector at 280 nm have shown the presence of some priority phenolic pollutants.

HLA-DQ alpha genotype and allele frequencies in Malays, Chinese, and Indians in the Malaysian population

Koh CL, Benjamin DG

Hum. Hered., 1994 May-Jun;44(3):150-5.

PMID: 8039798

The HLA-DQ alpha genotype and allele frequencies in 130 Malays, 125 Chinese, and 137 Indians in the Malaysian population were determined using a commercial HLA-DQ alpha DNA amplification and typing kit which distinguishes 6 alleles (DQA1.1, DQA1.2, DQA1.3, DQA2, DQA3, and DQA4) and 21 possible genotypes at this locus. All 21 genotypes were encountered in the Malay and Indian samples, but DQA1.1,DQA1.3 and DQA2,DQA2 genotypes were absent in the Chinese sample. In all three ethnic groups, the numbers observed for the various DQ alpha genotypes were in accordance with those expected from Hardy-Weinberg equilibrium. The allele frequencies observed in these three groups were significantly different to allow them to be distinguished as distinct populations. For the Malays, Chinese, and Indians, heterozygosity values at this locus were 0.77, 0.77, and 0.83, respectively, and values of the power of discrimination were 0.91, 0.90, and 0.94, respectively. These population data will enable the HLA-DQ alpha locus to be used as a marker in forensic identity testing in Malaysia.

Goh CL, Ng SK

Derm Beruf Umwelt, 1988 Nov-Dec;36(6):186-7.

PMID: 3069433

A young Malay female presented with a bullous eruption as a manifestation of contact allergy to cinnamic aldehyde in cinnamon. The clinical and histological features resembled bullous pemphigoid but immunological markers for pemphigoid were absent. The patient responded to a short course of oral steroids. Contact allergy can mimic pemphigoid.

Med J Malaysia, 1982 Mar;37(1):70-1.

PMID: 7121352

The serum alpha-1 acid glycoprotein of 9 euthyroid subjects, 14 hypothyroid patients and 21 hyperthyroid patients was determined by radial immunodiffussion in agar plates. The serum alpha1 acid glycoprotein level in both the hypothyroid and hyperthyroid patients were significantly lowered when compared to the euthyroid subjects. There was no significant correlation between the alpha-1 acid glycoprotein level mid the Liothyronine resin uptake (T3 resin. uptake) and the serum total Thyroxine Iodide (T4I) level.

An evaluation of the modified Airway Management Device

Chiu CL, Wang CY

Anaesth Intensive Care, 2004 Feb;32(1):77-80.

PMID: 15058125

This is a preliminary report on the use of the modified Airway Management Device in 50 spontaneously breathing patients undergoing elective day care surgery. We were successful in establishing a clear airway in all 50 patients, 46 of these patients had a patient airway on the first attempt. All patients were successfully managed with the Airway Management Device throughout the surgery. Partial airway obstruction during maintenance of anaesthesia occurred in three cases requiring only minor manipulations. Our result showed that the Airway Management Device may be used as an alternative airway management in anaesthesia.

Morphotaxonomy based on phenotypic traits of immature hard ticks (Acari: Ixodidae) is a skill challenge and has prompted many inexperienced acarologists to adopt DNA-based methods for identifying and discriminating the species. The aim of this study is therefore to utilize COI gene for verifying the morphological status of Haemaphysalis ticks in Peninsular Malaysia. A total of 19 on-host ticks collected from four localities were first identified using specific illustrated taxonomic keys that lead to the genus of Haemaphysalis. Genotypic traits of tick species were then verified molecularly based on cytochrome oxidase subunit I (COI) gene using polymerase chain reaction and direct sequencing. Clustering analysis was carried out by constructing a phylogenetic tree to determine the genetic variation and diversity of local Haemaphysalis ticks. Based on external morphological characterizations, all immature ticks were successfully identified down to the genus level only. Molecular analysis of the genotypic using COI gene revealed 16 individuals (84%) as Haemaphysalis hystricis, and three individuals as H. humerosa with sequence homology of 97-99 and 86-87%, respectively. Haemaphysalis hystricis were clustered in their respective monophyletic group in the phylogeny trees with a bootstrap of 100%. Furthermore, a low intraspecific variation (<0.3%) was observed among Malaysian H. hystricis but high interspecific value (>15%) recorded. This study morphologically and molecularly confirms the presence of H. hystricis in Malaysia and the findings will add value to the existing knowledge in identification of ticks in this country.

The role of acute internal medicine service in handling burden of medical access block in a tertiary hospital, Hospital Melaka experience

Adznan NUH, Gan CL

Med J Malaysia, 2021 Jan;76(1):68-72.

PMID: 33510112

INTRODUCTION: Access block is a major problem faced by most hospitals. It has led to congestions in emergency departments (ED) leading to sub-optimal or delayed treatment. Inevitably the spotlight falls on medical department, being accountable for the highest proportion of access block in ED.

MATERIALS AND METHODS: This is a retrospective study looking at data collected during office hours on 79 working days, excluding weekends and public holidays in Hospital Melaka, Malaysia. Details on all medical access block cases that were reviewed were recorded including their locations, diagnosis, disposition decisions and if they received specialist input at the time of their initial assessment by the medical team in ED. The aim is to revolutionise patient admission flow by offering early specialist care with rapid assessment, investigation and treatment. Hence, improving the overall treatment efficiency and reduce medical access block.

RESULTS: There were 1321 admissions. A total of 82% of the patients were admitted to the medical wards while 13% of them were given acute treatment in ED and discharged home with appropriate follow ups. We managed to resolve 18% of medical access block by re-triaging our cases and offering timely acute medical treatment. Nearly 90% of patients received first hand medical specialist input during the initial assessment by the Acute Internal Medicine (AIM) team in ED.

CONCLUSION: The significant resolution in medical access block with active screening, re-triaging and management of patients by the AIM team allows a more optimal hospital bed management. Patients also receive timely access to medical intervention with specialist care and stable patients can benefit from early supported discharge.

Psychotherapeutic management of a potential spirit medium

Woon TH, Teoh CL

Aust N Z J Psychiatry, 1976 Mar;10(1A):125-8.

PMID: 1065324

Psychotherapeutic management of a potential spirit medium (shaman) in a modern University Hospital setting in Malaysia is described. Magical thinking, projection and spirit possession (trance state) occur during management. Discussion of management was based on what Heinz Wolff described as the psychotherapist's functions of (1) psychodynamic understanding; (2) the therapeutic function; and (3) the developmental function. This patient did not conform to the general criteria of a suitable patient for psychotherapy. But her willingness to engage in therapy contributed to a satisfactory outcome. The therapist's growth in cross-cultural therapeutic encounter seems to be prominent.

Fulltext Do statins adversely affect the HbA1c of diabetic patients?

Son WD, Teng CL

Malays Fam Physician, 2017;12(1):39-40.

PMID: 28503276

This paper discusses the adverse effect of statins on the HbA1c levels of diabetic patients. Studies have shown that statins may slightly worsen the HbA1c level. The effects vary depending on the type of statins, the dosage and the duration of therapy. However, it has been confirmed that statin use has benefits that outweigh its harms. Therefore, a diabetic patient should be given advice on the need for appropriate lifestyle changes and the importance of continuing the statins.

Fulltext Hepatoprotective Effects of Morinda citrifolia Leaf Extract on Ovariectomized Rats Fed with Thermoxidized Palm Oil Diet: Evidence at Histological and Ultrastructural Level

PMID: 31827717 DOI: 10.1155/2019/9714302

Morinda citrifolia (Rubiaceae) or Noni was previously reported to have leaf with broad therapeutic property whereas the fruit was rarely described as medicinal. Ironically, extensive research and review has been done on the fruit and little was known about the therapeutic activity of the leaf as a medicinal food. The aim of this study was to investigate the therapeutic effects of Morinda citrifolia (MC) ethanolic leaf extract on the hepatic structure and function in postmenopausal rats fed with thermoxidized palm oil (TPO) diet. Thirty eight female Sprague Dawley rats were divided into five groups: sham (Sham), ovariectomized (OVX), ovariectomized and treated with simvastatin 10 mg/kg (OVX+ST), ovariectomized and supplemented with low dose MC 500 mg/kg (OVX+MCLD), and ovariectomized and supplemented with high dose MC 1000 mg/kg (OVX+MCHD). All the ovariectomized groups were fed with TPO diet whereas the Sham group was fed with normal diet. Consumption of TPO diet in postmenopausal rats resulted in obesity, significantly elevated (P < 0.05) liver oxidative stress marker; malondialdehyde (MDA), diffuse microvesicular steatosis, and defective mitochondria. Treatment with MC leaf extract prevented hepatic steatosis by significantly increasing (P < 0.05) the liver antioxidant enzyme SOD and GPx, significantly increasing (P < 0.05) ALP, decreasing liver lipids infiltration, preventing mitochondrial damage, and overall maintaining the normal liver histology and ultrastructure. In conclusion, we provided detailed histological and ultrastructural evidence showing hepatoprotective effects of MC leaf extract through its antioxidant mechanism.

PMID: 28671308 DOI: 10.1111/cobi.12978

The commercial captive breeding of wildlife is often seen as a potential conservation tool to relieve pressure on wild populations, but laundering of wild-sourced specimens as captive bred can seriously undermine conservation efforts and provide a false sense of sustainability. Indonesia is at the center of such controversy; therefore, we examined Indonesia's captive-breeding production plan (CBPP) for 2016. We compared the biological parameters used in the CBPP with parameters in the literature and with parameters suggested by experts on each species and identified shortcomings of the CBPP. Production quotas for 99 out of 129 species were based on inaccurate or unrealistic biological parameters and production quotas deviated more than 10% from what parameters in the literature allow for. For 38 species, the quota exceeded the number of animals that can be bred based on the biological parameters (range 100-540%) calculated with equations in the CBPP. We calculated a lower reproductive output for 88 species based on published biological parameters compared with the parameters used in the CBPP. The equations used in the production plan did not appear to account for other factors (e.g., different survival rate for juveniles compared to adult animals) involved in breeding the proposed large numbers of specimens. We recommend the CBPP be adjusted so that realistic published biological parameters are applied and captive-breeding quotas are not allocated to species if their captive breeding is unlikely to be successful or no breeding stock is available. The shortcomings in the current CBPP create loopholes that mean mammals, reptiles, and amphibians from Indonesia declared captive bred may have been sourced from the wild.
